Breath-hold effects on lung blood flow using a safe imaging method
Part of Lungs & breathing clinical trials.
This study tests how holding your breath after breathing in versus breathing out affects blood flow in your lungs. It uses a safe, noninvasive imaging technique called electrical impedance tomography (EIT) with a small amount of saline (saltwater) given through an IV. The results may help doctors better understand lung function in healthy people.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 65 years old.
- You can hold your breath for at least 8 seconds after breathing in and after breathing out.
- You do not have any serious heart or lung conditions.
- You are able to give written consent and are comfortable with an IV and wearing a small electrode belt on your chest.
- You are not pregnant or breastfeeding, and you do not have any skin or chest issues that would prevent the electrode belt from fitting properly.

This study tests whether a special imaging technique called EIT (electrical impedance tomography) combined with a safe contrast injection can measure blood flow in the lungs of patients on breathing machines. If it works, it could help doctors better manage critically ill patients.
This study tests a new, radiation-free imaging method (3D EIT) to see how well it measures lung ventilation compared to a standard 4D-CT scan. It may help doctors in the ICU assess lung function more safely and frequently in the future.
This study uses a special MRI scan with a harmless gas to take pictures of your lungs. It may help doctors see how well your lungs are working, which could guide future treatments.
This study tests a new method using a saline solution and a special imaging belt to quickly diagnose pulmonary embolism (a blood clot in the lungs) in people with acute breathing problems. If successful, it could provide a faster, safer alternative to standard CT scans.
This study tests a new, less invasive method using electrical impedance tomography (EIT) to monitor blood flow in the lungs compared to the standard pulmonary artery catheter. It might help doctors manage your care with fewer risks.
This study tests a new, noninvasive way to measure lung function in people with pulmonary hypertension (high blood pressure in the lungs). It uses a belt with electrodes placed around your chest during a standard heart catheterization procedure.
